To all whom t may concern.' I

Be it known that-I, Emmi: B. Kanar, a

-ci-tizen .of the United States, residing. at

combustion engines, the invention having reference more particularly toimproved means for feeding and 'atomizing the liquid hydro-carbon andmixing it with air.l i

The object of the invention tti-'provide an 'improved' carbureter ofsimple construetion that will be adapted to be produced at relativelysmall cost, and be` so constructed l as' to be highly eiiicient andeconomical in the-use of the hydroicarbon in the explosive mixture; afurther object being to providea carbureter that will be so 'constructedthat the 'various parts thereof can be readilyjadjusted, 'or taken apartfor the. purpose of cleaning' the apparatus; a still further objectbeing to provide a carbureter that will be adapted to be repaired incaseof accidental damage thereto without discarding parts that may escapedamage.

The invention consists in a. carburetor of novel construction comprisingprimary feeding and atomizingapparatus, and adjustable detachableauxiliary" feeding and atomizing apparatms;` and the invention consistsfurther in the novel parts, and the,

combinations and arrangements of .parts, as

hereinafter particularlydescribed and claimed. -z

Referring to the drawings, Figure 1 is a -vertical central sectionalview of the improved carbureter as preferably .constructed; Fi 2 ahorizontal section on the line A. A ing. 1; Fig. 3 a' horizontal sectionon the line B B in Fig. 1 inverted, the

A suitable lever 18-ismounted .on a pivot 19 in the valve-chest and extends into the interiorofthereservoir-and has .an annular float QO'secured thereon, the leverextending beyond the pivot and having an end 21- 4suit- 'andapproximately U-shaped with its ends extending upwardly, an 1n,let-endsection 24 being connected to one end, and-:an outlet end section 24beingconnected to the ,othercnd ofthe section 24. The lowermost portion'of the mixing .tube'is central on 'the cover 22 and atube Q5 is castinteably connected with the stem 16'so `as to which is seated grally onthe central portion of the cover at the under side thereof, and it'extends through theinterior" of thc reservoir and through thelfl'oatandthe bottom 1, the -tube having collar .26 formed thereon' that is seatedupon the. bottom, the projecting end portion 27 of the tube having a nutQS screwed onto it and against thcfuudcr side,

. A valve-chest 42 is cast'inte 4lly with the mixing tube secti`on'24'`and il; a bushing 43 screwed adjustably into' the, under' Side lthereofina suitable opening, an air-inlet valve 44 being'removably seatedfupo'n the upper or inner end of the bushing and provided with a guidestem "45 that v1s movable in a hollow guide 46 adjustably supported inthe top of the valve-chest, a spring 47 being seated upon the valve andaoamst the inner en d of the guide for nrmallby holding the valve to itsseat, the valve being adapted to be' opened only-'atf'relatively highspeeds ofthe engine, as an auxiliary valve for admitti an l increased.of air or carburet airitothe tube.

In order that thdrilmitted by the 'auxiliary air valve may be morehighly carbureted than would be possible by means .of the fuelfeedingapparatus, a suitable valve'fchest .4 8is provided which has atube'ivst ion one side thereof and'adapted the bosses on the `side ofthe reservoir, the tube A'as illustratedfbein screwed into the boss4,and as will lbe un erstoodz in case. the: valve-chest 3 interferes-with`existingconstruction of vthe engine. or other machlnery, thereservoir 4may be turned so as to 'move the valve-chest e" in'respectively that afford -34, is fed out of the `way and the cover 22adjusted ac- V and.;either one of the-plugs 1 0 ay V'beifefino'ved. andthe tube 49 inserted-in its', @16Std With Plug- .Y a packing-,box 50 on?is a packing-gland 'L--i-'Atube 52is inserted cordinl and llgri yyplace,"the boss4'then being itsupper end .in Whichthroxgh 'the' glandAand screwed adjustably into the valve-chest`48..beyond .the bottom i of.the4 packing-box, :the 52 having .a spraying nozz e 53 'on its upper endwhich preferably has sockets54 therein to receive a suitable tool forturning the tube so as to lraise or lower it. The upper portion of thetube 52h35 external screw-threads 55 vthere#` on on'which a dish-shapeddeiector 56is adjustably screwed, so that it may be raised or loweredwith respectv to the nozzle and is prevented -froni v accidentalmovement by lmeans of a lock-nut 57 screwed onto the tube against thedelector. The deflector is somewhat larger in diameter'- thantheinterior of the bushing 43h-nd is arranged at a suitable distance belowthe bushing. The lowerrportion of the valvechest 48` has an extension58-thereon which has screw threads 59 therein,

-a packing-nut'4 60 being placed on the end portion of the extension.Ava-Ivestem 61 is inserted through the packing-,nut and has screwthreads 62 thereon in contact with the screw threads 59, the valve sternextending .o he valve-chest 48has` up through the tube 52 and having aneedlepointvalve 63 on its upper end extending into the orifice of fthenozzle 53, for varyingthe area of the orifice and coperating withthe'nozzle to assist in atomizing the hydrocarbon which may be' drawnfrom the reservoir by the higher velocity of the air enterinfr 'theauxiliary air valve, the dish-shaped de ector serving to create partialvacuum at the nozzle 53, so that the air passing between .the deflectorandthe lower end of the bushing 43 when entering the'bushing'will themore effectually suck up' the hydro-carbon, the valve 44 assisting alsoin atomizing the liquidl as it passes with the air into the'mixtube. Theoutlet end 64 of the mixing tube 'section 24" is suitably adapted'to beconnected withfan explosive engine, or a pipe leading thereto. Thesection 24 has a rock shaft 65 mounted therein to which a butterflyvalve 66 is secured, the" shaft having an operating arm-67 thereon.

In practical use',v while the engine is being started and when runninglat relatively slow speed, the hydro-carbon which is maintained at thedesired -level in the" reservoir by means of the float therein,approximately ai) the level of the top of the nozzle y means of thevalve 41 and taken up and atomized in the tube 25 byV means of the airpassing through the tube into the mlxingtube section 24 from which thecarbureted air is drawn through the tube section 24 *into the enginecylinders. `When the suction increases due to increasing speed of theengine, the" auxiliary ,.valve 44 is -brought intoaction and the airdrawn in at higher velocity draws the hydro-carbon from the nozzle 53asbefore explained, so' that the auxiliary, `Feeding is automaticallybrought into action as required by the engine, and its actiondiscontinued automatically when the engine is again reduced in speedbelow the normal rate. It Vwill be understood that the top of the nozzle53 is slightly higher than justable nozzle that is below-the open bottomflector supported on the nozzle, and a valve in the nozzle.
